This invention appertains to new and useful improvements in burners ofthe type especially devised for burning apricot pits, of which there isan abundance in some localities.

The principal object of the present invention is to provide meanswhereby pits can be burned in ranges, fire places, and elsewhere. I

Another object of the invention is to provide an apparatus whereby pitscan be burned in a useful manner, including means whereby the pits areuniformly fed'to a burner structure.

Other important objects and advantages of the invention will becomeapparent to the reader of the following specification.

' 'In the drawings:

Figure 1 represents a front elevational view showing a range equippedfor burning pits and the dispenser situated adjacent the same.

Fig. 2 is a vertical sectional view through the pit burner.

Fig. 3 is a fragmentary horizontal section on line 3-3 of Fig. 2.

Fig. 4 is a fragmentary-sectional view taken substantially on line 4-4of Fig. 1.

Fig. 5 is a fragmentary sectional view taken substantially on line 55 ofFig. 1.

Fig. 6 is a fragmentary edge elevational View of one of the ventilators.

Fig. 7 is an end elevation of one of the ventilators.

Fig. 8 is a fragmentary sectional view of the hopper.

Fig. 9 is an inside elevation of one of the end walls of the burner.

Fig. 10 is an end elevation of the double type burner.

Fig. 11 is a section on line ll|l of Fig. 10.

Fig. 12 is a side elevation of the fireplace type burner.

Fig. 13 is a section on line l3-l3 of Fig. 12.

Figure 14 is a fragmentary vertical sectional view through the hopperdisclosing a modified form of closure for the chute.

Figure 15 is a perspective view of the closure removed from the hopper.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Fig. 1, that numeral 5 generally refers to the dispenserwhich consists of the removable top 6 on the shell I, which shell isprovided with the bottom 8 in which is the discharge opening 9 (see Fig.8). A vertically adjustable spreader in the dispenser 5 just above thedischarge opening 9, prevents the pits from jamming in the dischargeopening, this spreader being denoted by reference character Ill.

The dispenser5 is mounted upon legs l suitably secured to the. floor asat l2. A spout l3 extends from the discharge opening 9 and 5 through thetop M of the range generallyreferred to by numeral l5 so that itsdischarge end is located immediately over the pit burner, generallyreferredto by the numeral I 6. This pit burner is installed in the firebox l'lof the range 0 after the usual grate has been removed.

The pit burner consists of the side walls l8|8 and the end Walls l9- l9.Eachof these walls is provided with a plurality of ventilating openings20. The side walls and the upper ends of'15 supporting legs 2| securedthereto as at 22. The upper edges of the end walls and sidewalls areprovided with inwardly disposed and apertured lugs 23, though a secondburner generally denoted by the character IG can be inverted and 0placed upon the one shown in Fig. 2 to convert the same into a doubleburner. In mounting the second burner, generally referred to bynumeral-24'upon the burner l6, it is preferablyihat the ventilatorsgenerally referredto by 'the nu meral 25 be reversed from the positionshown in Fig. 2, due to the inversion of the unit 24.

As can be seen in Fig. 9, the vertical edge portions of the downwardlytapering end walls l9 are provided with ribs 26 each of which isprovided with a longitudinally extending V- groove 21. The lower edge ofthe end wall I9 is also provided with the rib 26 having the V- groove 21therein.

The meeting edge portions of the side and end walls are joined togetheras shown in Figs. 4 and 5. The ends of these side walls are beveled asat 28 to engage into the V-grooves 21, and bolt members 29 are disposedthrough allotted bores in the meeting edge portions so as to secure theside and end walls in abutting relation.

Each of the ventilators. 25 consists of a longitudinally andtransversely curved plate 30 having a plurality of ventilating openings3| therein. Each of these ventilators 30 is provided with a headformation 32 at one end, and each of these head formations is providedwith a reduced extension 33 having an upstanding lug 34 thereon, at itsextremity.

The head 32 is furthermore provided with the depending legs 35 having atransverse opening therein for receiving the bolt 36. This bolt has ahead 31 which engages into one of the ventilating openings 20 of thecorresponding side wall l8 so as to prevent rotation of the ventilatorand a nut 38 on the bolt prevents displacement of the bolt from the leg35.

When the burner 25 (see Fig. 10) is used in superimposed relation on thelike constructed burner IS, the lugs 23 of the burners are boltedtogether as at 39. (See Fig. 11.)

Fig. 12 shows a fire place form of burner consisting of the rear wall 28and the front wall 20. These walls have their ends connected by the endwalls l9a. These rear and front walls are equipped with the ventilators38. A slotted bottom 26a is provided for this type of burner, and servesas a grate.

The only substantial difference in the fire place type of burner overthe burner shown in Fig. 2, is that an upward extension wall generallyreferred to by numeral 40 is provided, the same being ornamented bysuitable edge portion formations and block designs, and this wallextension 40 is provided with inwardly disposed lugs 4| which are boltedas at 421 to the lugs 43 at the upper edge of the front wall 20'.

It will be observed, that the ventilators 38 or 25 are arranged, someprojecting inwardly from the front wall and the others projectinginwardly from the side wall in interlapping relation to the firstmentioned ventilators, so that the pits as they are. burning, mustfollow a tortuous path downwardly through the burner.

A modified form of agitator and closure for the chute l3 as shown inFigure 8 is disclosed in Figures 14 and 15 wherein reference character5a discloses the hopper from which depends the chute |3a and over theupper end of this chute and upon the floor of the hopper 5a is slidablydisposed the closure plate lGa, the inner end of which is provided atits corner with upstanding ear members bb while the other end is rolledupwardly as at 0. Thus it can be seen that when the plate Illa is shovedto the dotted line position shown in Figure 14 the chute will be closedoff from the hopper and the roll 0 will prevent the plate from entirelyentering the hopper as it will abut the outside of the hopper. When theplate is grasped by the roll 0 and pulled outwardly the ears bb willserve to agitate the pits so that they will readily discharge throughthe chute I311 and when the plate has been moved to its full extent asshown in Figure 14 the ears b-b will then serve as stops, preventingcomplete displacement of the plate from the hopper.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed as new is:

1. A pit burner comprising a hopper-like structure open at its top andbottom, said hopper-like structure provided with a multiplicity ofopenings in the side walls thereof, pit supporting plates mounted in thesaid hopper and projecting from opposite side walls of said hopper ininterlapping spaced relation.

2. A pit burner comprising a hopper-like structure open at its top andbottom, said hopper-like structure provided with a multiplicity ofopenings in the side walls thereof, pit supporting plates mounted in thesaid hopper and projecting from opposite side walls of said hopper ininterlapped spaced relation, said plates being longitudinally curved.

3. A pit burner comprising a hopper-like structure open at its top andbottom, said hopper-like structure provided with a multiplicity ofopenings in the side walls thereof, pit supporting plates mounted in thesaid hopper and projecting from opposite side walls of said hopper ininterlapped
